#     fs: fix fd table size alignment properly
#     
#     Jason Donenfeld reports that my commit 1c24a186398f ("fs: fd tables have
#     to be multiples of BITS_PER_LONG") doesn't work, and the reason is an
#     embarrassing brown-paper-bag bug.
#     
#     Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the
#     reason they might not be aligned is because the incoming 'max_fd'
#     argument might not be aligned.
#     
#     But aligining the argument - while simple - will cause a "infinitely
#     big" maxfd (eg NR_OPEN_MAX) to just overflow to zero.  Which most
#     definitely isn't what we want either.
#     
#     The obvious fix was always just to do the alignment last, but I had
#     moved it earlier just to make the patch smaller and the code look
#     simpler.  Duh.  It certainly made _me_ look simple.
#     
#     Fixes: 1c24a186398f ("fs: fd tables have to be multiples of BITS_PER_LONG")
